Datuo-class rescue and salvage ship

The Datuo class is a class of little known rescue and salvage ships (ARS) built in the People's Republic of China (PRC) for the People's Liberation Army Navy (PLAN). The exact domestic Chinese type designation remains unknown, and this class is identified by its NATO reporting name Datuo class, or 大拖 in Chinese, meaning "big tug". Specification: Length: 60 meters (196 ft 10 in) The Datuo class in PLAN service is designated by a combination of two Chinese characters followed by a three-digit number. The second Chinese character is Tuo (拖), meaning Tug in Chinese, because these ships are rescue tugs, and thus can also be used as tugs. The first Chinese character denotes which fleet the ship is in service with, with East (Dong, 东) for East Sea Fleet, North (Bei, 北) for North Sea Fleet, and South (Nan, 南) for South Sea Fleet.
